Perfect place to visit for an afternoon especially if you are on a budget as we were. Great view with some plaques to point out some of the area's features and history.

This is something unique for the city. You go to an observation level inside the gold ball for a view over the city. It is free to do and there is a place to eat inside, too, on another level. Parking is not the best...More

The sunsphere was an interesting tower. We stayed overnight in Knoxville and decided to check it out as it was free and close by. The tower is located in worlds fair park. It is a little eerie as it is very empty and no people...More

We had a small meeting on the 6th floor of the Sunsphere. It's a very unique space, unlike anything else I've ever experienced. The view is great.

Another free offering by the great city of Knoxville! Take an elevator up to the all glass 360 degree view of Knoxville. It made my knees wobble because we were so high up!!

The hours for the Sunsphere were 8 am to 10 pm. Only one elevator was working so it was a few minutes wait to get up and come down but it was definitely worth the wait as the view of the city was amazing!

The Sunsphere is worth visiting just for the views and to learn about the area and why it was built. There isn’t really anything else there, but it is a short walk from Market Square and worth the visit.

We were looking for free things to do in Knoxville. It was in walking distance of other free things. It allowed us to see the whole city from high up in about 2 minutes. My daughter was a bit scared. The outside of the Sunsphere...More

Yes, to get inside it is free and the observation deck is also free. I believe there was a restaurant on one of the levels, which obviously would cost you, and you might have to pay for parking nearby to check this out, but... More
